HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 408,773, dated A ugust13, 1889.

Application filed July 26, 1887- Serial No. 245,309. (No model.)

Be it known that I, SAMUEL S. WALES, of Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and-usefulImprovements in Heating- Stoves, of which the following is aspecification.

My inventionrelates to certain improvements in heating-stoves5 and itconsists, generally, in the combination and arrangement hereinafterdescribed, and particularly pointed out in the claims.

In the drawings which form a part of this specification, Figure 1 is afront elevation of my improved stove. Fig. 2 is a vertical crosssectionof the same. Fig. 3 is a vertical longitudinal section; and Fig. 4 is adetail.

The lower portion of the stove is constructed in the ordinary manner,having the fire-pot 2 and grate 3, and ash-pan 4, made after anywell-known pattern of heating-stoves.

6 is a ring or band, preferably of cast metal, which fits the upper rimof the fire-pot and may be made either round or square to suit the styleof stove. Upon the upper surface of this rim I prefer to provide twosets of flanges, the flange 7 at the inner edge or around the opening inthe rim, and the flange 9 at or near the outer edge.

10 is a combustion-chamber, consisting preferably of a sheet-metal drumthat is placed above the fire-pot and rests upon the top of the rim 6,just within the flange 7. This combustion-chamber is closed at the topand provided with a smoke or draft pipe 12.

14 is a drum, preferably formed of sheet metal and extending over thecombustion chamber and resting upon the rim 6, just within the flange9,leaving an annular space between the drum and the combustion-chamber.An inlet-opening 18, covered by a suitable damper, is formed near thebottom of the drum to provide for the admission of the outside air. atthe top of the drum, and pipes may be placed over these openings and theheated air from the drum conveyed to other rooms.

22 is a fuel-door in the wall of the outer drum or casing surrounded bya chute 23, extending from said door across the annular space betweenthe drums and opening into the combustion-chamben The fuel may be thetop of the combustion-chamber.

Outlet-openings 20 are provided fed through this door and chute into thefirepot.

The inner drum, forming the combustionchamber, is preferably ofconsiderably less height than the outer drum, so that an airspace ofconsiderable size is provided above The inner drum is also preferablyprovided with a flat top and the outer drum with a door 16in its wallnearly opposite this top, so that the chamber above the inner drum isadapted to be used as a heating-oven. By opening the door 16 articlesthat it is desired to heat may be placed in this chamber on the flat topof the inner drum. The chamber thus serves the double purpose of aheating-oven and an air-heating chamber, fromwhich the air after beingheated may be conveyed to any desired point. The annular space betweentwo drums forms a continuous air-heating flue, into the lower part ofwhich the air is admitted through the draft-openings 18, and wherein itis raised to a high temperature as it passes up over the wall of theinner drum or combustion-chamber. The smoke-flue preferably passes outat the top of the combustion-chamher and passes through theheating-chamber, so that the heat radiated from it aids in increasingthe temperature of the air in this chamber. chamber may be used inconnection with any kind of stove, self-feeder, base-burner, &c. Theconstruction is verysimple and inexpensive.

The base of the stove radiates heat to the This arrangement of theheatingroom in Which it is loeated,while the heating- 1 drums, withoutlessening the radiating effect of the base of the stove, in additionheat a large supply of air which may be thrown out into the same room orconveyed to other rooms of the building' I claim as my invention- 1. Ina heating-stove, the combination,with the base 2, constituting a surfacefor directly radiating heat into the room, of the rim 6,

inlet 18 in its side above the base and rim 6 and opening into the spacebetween the two drums and provided witha closed top having exit-openings20 for the attachment of conducting-fines, and having a door 16 abovethe flat top of the inner door, all substantially as and for thepurposes set forth.

2. The combination, in a heating-stove, of the fire-pot 2, the rim 6,fitted to the top of said fire-pot and projecting inwardly over thechamber of the same and formed with the flanges 7 and 9, the drum 10,having a closed top and resting on said rim next to the flange 7, thedrum 14, resting on said rim next to the flange 9 and provided withinlet-openings 18
